초록
본 연구는 담수직파재배에서 완효성질소비료인 Latex coated urea(LCU)와 Meister10(MS10)의 효과를 구명하기 위하여 포장시험으로 조생종인 중화벼를 공시품종으로하여 무질소구, 요소구, LCU구, MS구로 처리하여 벼의 생육, 수량 및 수량구성요소, 질소흡수량 및 이용율, 시험전후 토양의 화학적특성을 조사한 결과는 다음과 같다. 초장과 분얼수는 요소구보다 LCU구와 MS10구가 높았고, MS10구는 LCU구보다 초장은 비슷했으나, 분얼수가 높았다. 입모수는 요소구, LCU구, MS10구간에 차이가 없었다. 간장은 요소구 보다 LCU구와 MS10구가 높았고, 수장은 요소구, LCU구 및 MS10구간에 통계적 유의성이 없었다.
This study was conducted to find out the effect of slow-release nitrogen fertilizer, such as latex coated urea(LCU) and Meister10(MS10) on direct seeded rice in flooded soil(FS). Junghwabyeo, and early maturity rice cultivar grown on the plots which were treated with None-nitrogen, urea, LCU and MS10 plot. Growth characteristic, yield and yield components were investigated. Nitrogen uptake-efficiency and physico-chemical properties of soil before-after experiment were analyzed. Plant height and number of tillers
